将大型视频上传到asp.ngj中的数据库

Question

我搜索了如何使用asp.net将大于4MB的大视频大小保存并存储到数据库中。我尝试了很多代码。我也用过：

<httpRuntime maxRequestLength="102400" executionTimeout="3600" />


<security >
  <requestFiltering>
    <requestLimits maxAllowedContentLength="1024000000" />
  </requestFiltering>
</security>

这不行。它告诉我消息：

超时已过期。操作完成之前经过的超时时间或服务器没有响应

到目前为止，我将数据列更改为varbinary（MAX），但我无法存储大小为100MB的大文件。

我的代码

        BinaryReader br = new BinaryReader(fs);
        Byte[] bytes = br.ReadBytes((Int32)fs.Length);

        //insert the file into database

        string strQuery = "insert into Image(Img_Title, Img_Extension, Img_Data, Course_code, Course_num, Img_Description, Keyword , Date)" +

Answer 1

尝试更改用于将大文件存储为图像的字段的数据类型，而不是二进制

并在您的代码中使用：

cmd.Parameters.Add("@PARAMETER", SqlDbType.Image).Value = bytes;

而不是SqlDbType.Binary

另请注意，如果您需要更多时间，则应增加连接字符串中的超时

value =“Server = ###。###。###。###; Database = $$$$$$$; User ID = ##; Password = $$$$$$; Connection超时= 1200“
